TOSCANO, Rafaela Della Giacoma Prado e ANASTASIO, Adriana Ribeiro Tavares. Auditory abilities and acoustic immittance measures in children from 4 to 6 year old. Rev. CEFAC [online]. 2012, vol.14, n.4, pp. 650-658. Epub 05-Ago-2011. ISSN 1982-0216. http://dx.doi.org/10.1590/S1516-18462011005000080.
PURPOSE: to evaluate the performance of auditory abilities and conditions in the middle ear of children from 4 to 6 year old. METHOD: we applied the tests in order to detect sound (pediatric audiometer in 20dBHL), the Simplified Assessment of Auditory Processing (SAAP) and the acoustic immittance measures (handtymp with a probe of 226Hz). In order to compare the results from the tests of auditory abilities and measures of acoustic impedance we applied Fisher's exact test with significance level of p <0.05. RESULTS: the study involved 61 children with a mean age of 5.65 years. There was some alteration in at least one of the investigated auditory skills in 24.6% of the children. Tympanometry was altered in 34.4% of the children and 64% were classified on the "fail" criterion for the measure of ipsilateral acoustic reflex. Younger children had higher incidence of middle ear disorders, but with no significant statistical difference between different ages as for the tests. CONCLUSION: younger children showed a higher occurrence of alterations in the tests of auditory abilities and measures of acoustic immittance. Research and monitoring programs for the conditions of the middle ear and auditory skills in preschool and school age can eliminate or minimize events that would alter the socio-linguistic development.
